It would happen for folders/file names with spaces. You'll have to enclose the file name in double quotes to fix it

oShell 	= CREATEOBJECT("WScript.Shell")
lcFileName = GETFILE("pdf")
* Enclouse into double quotes to avoid problem with spaces in file name
lcFileName = ["] + lcFileName + ["]
oShell.Run(lcFileName,1)

>Yes I retrieve the filename by Getfile() and the file can be open without problem outside VFP
>It seems to give me no problem with Jpg files while I got into problems when trying to open Xls or Pdf files
